Tool-holder.



of this stop is to limit the amount of movey pressingr a tool against said lever in advance nient of the tool support on its pivot, and to maintain the saine inproper position when tool has become short.

e t will be particularly noted that, Whatever the length of the tool, it always rests firmly and squarely against the upper s urface of the support, and that the support may yroclt about its pivot so as, to properly adjust itself to the pressure exerted by the screw l0. In this Way, abnormal strains in the tool' or holder are prevented. Furthermore, it will :be seen, practically the entire Wear cornes upon the support 3 rat-her than upon the body portion of the holder and, therefore, if the support becomes Worn from long nse,'it may be readily and cheaply renewed. l

' It will thusbe seen that I have provided a ver sini le and eiiicient device for fir-ml an rigid y holdingr the tool under all conditions, and supporting the'same against vibration, and it is thought that the numerous advantages of my invention will be readily appreciated by those skilled inthe art.

' What I claim is 1 l.` in a holder for lathe tools, a body adapted for attachment to the tool post or.

equivalent' fixture ota lathe. a tool supporting lever pivoted to said body, said body and lever having` vopposed surfaces forming walls ofqa tool slot, and means upon the body for pressiugfa tool against the lever f in advance of its pivotal point, whereby when thetool extends to the rear portions of' the slot, the 4rear end of the tool becomes gripped by said walls.
